bazza - the builder

Build up objects close to where they're being used.

customer = Customer.with.Order.with(:total => 22.21).thats.active.build

You can:

• specify defaults
  • can be overridden
• reuse builders
• chain builders
• specialise builders

An Example

customer = Customer.with.Order.with(:total => 22.21).thats.active.build

class Customer end

class Order end

class CustomerBuilder end

class OrderBuilder end

TODO

• Association:
  • single
    • implement responds_to whereever method_missing implemented
    • ponder adding default hash param to #with
    • dynamically add the methods to builder, based on instance being built?
  • many
    • Build multiple: Customer.with.two.Orders
    • linguistics gem for text to number conversion
• Specialisation
  • infer #make#{Something} method convention for specialisation methods on builder?
• #initialize and #build should be already available to builder
• #with and #thats can't be combined at present
• Reusing builders
• Replace String>>#to_class implementation from stack overflow article with a spec'd/tested version
• Alternative syntax:
  • Order.thats.active.build => Build.order.thats.active
  • Advantage is Class extension no longer needed
  • How to know when to build the instance?
